Two field experiments were conducted at the private Farm at Al-Delingat, Al-Bhyra governorate, Egypt during two successive seasons (2014 and 2015) to study the effect of some fertilization treatments (T1 (control) NPK recommended dose at 300 + 200 + 100 kg/fed of ammonium sulphate, calcium super phosphate and potassium sulphate, respectively, T2=3/4 NPK dose + 3g/l active dry yeast (ADY), T3=3/4 NPK dose + 200 mg/l citric acid (CA), T4=3/4 NPK dose +200 mg/l ascorbic acid (AA), T5= 1/2 NPK dose + 3g/l ADY+ 200 mg/l CA,T6= 1/2 NPK dose +3g/l ADY+ 200 mg/l  AA,T7=1/2 NPK dose +200 mg/l of each CA and AA, T8=1/4 NPK dose + 200 mg/l of each CA and AA+ 3g/l ADY, T9=1/4 NPK dose + 250 mg/l of each CA and AA and T10= 250 mg/l of each CA and AA+ 4g/l ADY.) The obtained results cleared that the significantly highest values of plant height, plant aerial parts fresh and dry weights, essential oil yield/plant, leaf green color degree and N, K and total carbohydrates %, resulted from T4 in addition to T1 in case of plant height, number of shoots/plant and P % and T10 in case of essential oil percentage at the two cuts in the both seasons.
